in such a case it would be great if you added a saw and square generator as well as the simplest fx (eg AM/FM) section
It is also a lot easier to turn a few knobs and flip a few switches than it is to point and click...

Bbe, that's already available, it's called the Z-5!
This is just the quadrature oscillator from the Z-5, this board outputs sine and square. The rest of the main Z-5 board has a saw and square LFO which is used to AM modulate the signals from the VCQO's via a VCA. And(or) you can FM modulate the signal with the 2nd input on the VCQO. Like I said, this is just the VCQO, which can be used in a number of other projects or a mini abstract generator can be made with a couple of these boards plus some other support circuitry.
Oh, I missed it .. your Z-5 definitely monster
Are you planning to develop Z-6 with motorized faders and buttons, or maybe Z-7 with digital potentiometers? It opens up many possibilities for the control of this generator, although it will not be a old school device from the 80sBbe, that's already available, it's called the Z-5!
Quadrature for color mod? Why? Even back in the day Laserium's color mod was "digital". Today with RGB systems you almost have to go digital...

Laserist, can you elaborate on this a little more. If I am trying to mimic an analog signal by using a DAC output for each of my colors why wouldn't I want analog directly? Yes if I am trying to get a very specific color I may want control of individual steps per color (digital) but if I just want a rainbow of colors to flood my pattern while being AM modulated around the pattern I can see the fun in true analog color modulation.
I guess my though is just because Laserium didn't do it doesn't mean there isn't a place for it today. There is room for all kinds of art performed in all kinds of different ways.

For color mod you're traditionally working with full on colors. A bipolar sine wave when you're driving a galvo to whip beam around isn't horrible, but it's not that useful for analog diode drivers, and the cosine output might generate something interesting, but only as a subset of what could be done...

Ok, so it looks like if we wanted to do this I would need to have about 10 boards printed. I'll take 4 and 6 for other folks. At 10 boards we'd be looking at $18.00 per board plus whatever it cost to ship to you. If you just want the board, no problem, it will come with a parts list and I'll put together a video on how to tune them. Note, you will need an oscilloscope.
Or, if you want a fully populated board that's tested and tuned it will be $55.00 plus shipping.
If anyone else signs up for one the price should drop a little bit. I figure by the end of next week I'll close this out, accept payment and get the orders put in. lead time would probably be about 3-4 weeks for the assembled boards and probably less for the bare boards.
Thanks!

Dz,
Could you please put me down for three of these, sorry I'm a little late to the party I'll take them fully populated please
Many Thanks
